Nejednaka

Nejednaka is a term used in mathematics to describe an inequality, which is a statement that compares two expressions and asserts that they are not equal. It is denoted by the symbols ≠ or ≠. For example, the statement "5 + 3 ≠ 7" asserts that the sum of 5 and 3 is not equal to 7.

Inequalities can involve various mathematical operations, including addition, subtraction, multiplication, and division. They are used to express relationships between quantities and are fundamental in fields such as algebra, calculus, and optimization problems.

In algebra, inequalities are often used to solve problems involving unknown variables. For instance, the inequality "x + 2 ≠ 5" can be solved by isolating the variable x, which results in "x ≠ 3". This means that any value of x other than 3 will satisfy the inequality.

Inequalities can also be used to compare the sizes of different quantities. For example, the statement "10 > 5" asserts that 10 is greater than 5, while the statement "3 < 7" asserts that 3 is less than 7.

In summary, nejednaka is a term used to describe an inequality, which is a statement that compares two expressions and asserts that they are not equal. Inequalities are fundamental in mathematics and are used to express relationships between quantities and solve problems involving unknown variables.
